Out of the box Evaluating risks
I evaluate risks.

Many risks have low impact. They have low frequency (say 1 in a million) or low severity (say cost $100 or less). 

I do not bother about risks with low impact. For example:

a) I leave my back pack unzipped because there is nothing valuable could be lost or stolen

b) I do not worry about being infected by mild covid, because they go away after a few days. 

I do not take the trouble to control these low impact risks. The cost of the control measures outweigh the loss that could happen. 

I do not want to zip my bag because I have other things to take care of, like holding to the rail on boarding the bus. I have only two hands and many things to do, apart from zipping the bag. 

Falling off the bus is more serious than losing some useless things in my back pack.

For the same reason, I do not want to wear a mask on the bus or train, because I do not have enough hands to put on the mask, tap the fare card, carry one or two bags and my mobile phone. 

Other people have their own priority. I leave them alone. They should also leave me along - and stop asking me to zip my bag or put on a mask.
